While I was visiting my sister one evening, I took out a candy
dispenser that was shaped like a miniature person. "How does that
thing work?" she asked.
As I turned the figurine's arm to pop candy out, my sister laughed. "I
see ... it's a lot like my husband," she said. "You have to twist his
arm to get anything out of him."
